Moving into operations

This site is under transfer into operations today.

System update

The software running the catalogue integration in the test portal has been upgraded. This upgrade brings the ability to work with parent/children relationships for datasets as well as to define collections withn the system. The content in the portal is still test data that are not necessarily GCW relevant. This will be changed once this portal moves from test to operations.

New functionality

A vaidation service for NetCDF/CF files have been added. You find this interactive service under the menu "Support". It will also check ACDD elements if requested. The purpose of this service is to help data providers to chech their products before they are made available. The service is available at https://gcw-test.met.no/dataset_validation/form.

A Failover operation has been scheduled on Thursday February 22 at 12:30 Norwegian time.

It will have a short, but widespread impact on network traffic in Oslo. Expected Maintenance Duration: 30 Minutes
 

In addition, this site will undergo scheduled maintenance on Monday, February 26.

Short interruptions in operation may occur during the whole day.

GCW/SLF software package

WMO Global Cryosphere Watch (GCW) is depending on a number of observing stations (CryoNet stations) for feeding the GCW value chain with observations. GCW has a requirement for both real time and archived data. In the period 2015-2017, GCW has been working with WSL/SLF to set up interoperability between the WSL/SLF data centre being responsible for one of the CryoNet stations. WSL/SLF has kindly agreed to make the software stack they have developed available for a wider community.

Under development

The old GCW Data Portal is available at http://gcw.met.no. This portal is still under development and active content management has yet not started. The Global Cryosphere Watch catalogue is yet not considered an operational service. It is populated with metadata harvested from a number of contributing data centres, but data remains in the original location and are served through the interfaces supported by the originating data centre.

How to encode data

The best way to integrate with the GCW Data Portal at the data level is to serve data (observational or analysed/simulated) through the Open-source Project for a Network Data Access Protocol (OPeNDAP). OPeNDAP and the Network Common Data Format (NetCDF) both use the Common Data Model which simplifies data handling. When serving data through OPeNDAP, data must be encoded according to the Climate and Forecast convention (CF). Starting with version 1.6 of the CF conventions, standardised approaches to encoding:

How to connect your data centre

The GCW Data Portal is a metadata driven data portal. This implies that data are hosted and served by contributing data centres which expose discovery metadata on the datasets. Once initiated, the GCW Data Portal regularly (once daily) harvests discovery metadata from the contributing data centres and ingests this in the GCW Data Catalogue which is integrated in this site.
